Anatomical Study of Cervical Vertebra in the White Albino Rat Males Treated with Lepedium Sativium Seeds Extract
The study was conducted to find out the effect of secondary compounds extracted from Lepedium sativium seeds on the phenotypic structure of the cervical vertebrae by measuring the weight and lengths of each cervical vertebra. The study was performed in the animal house of Department of Biology, College of Education for Girls, University of Kufa, it included the use of 40 Albino rat of the Sprague Dawley strain, one months old, the average weights range (200-250g).the were divided in to 4 equal groups, the first group included the control group, which was dosed orally with distilled water only, the second group was treated with cold aqueous extract of the Lepedium sativium seeds 50 mg / kg, the third group was treated with cold aqueous extract of the Lepedium sativium seeds 100 mg / kg, the forth group was treated with cold aqueous extract of the Lepedium sativium seeds 150 mg / kg of body weight. Each group was administrated from the first day to experiment and until the sacrifice of animals, which was in two stages on 30 and 45 days for each group. The study included measuring the weights of the cervical vertebrae, as well as measuring the lengths (length, width, dimeter) of the vertebrae. The statistical analysis of the current study results was showed significant increase in weights of the cervical vertebrae in the group treated with cold eqeous extract of Lepedium sativium seed at a concentration 150 mg / kg, compared to the control group. As the Average weight increases with increasing the concentration of the extract. Also, The statistical analysis of the current study results was showed significant increase in lengths of the cervical animals treated with extract of Lepedium sativium seed at a concentration 150 mg / kg, for periods of 30 and 45 days compared to the control group.
